Human language draws on a complex set of cognitive, motor and auditory skills. Some of these are found in other species but others are thought to be absent. There has been a burst of research in this area over the past five years, both in examining natural communication systems and also in the laboratory, exposing animals to human language. Most of the work has focused on analogies to syntax. Although many of the fundamental building blocks for basic phonological skills might be found outside humans, most aspects of core phonology have never been investigated. 相似文献

In recent studies, researchers have examined animals' use of absolute or relational distances in finding a hidden goal. When trained with an array of landmarks, most animals use the default strategy of searching at an absolute distance from 1 or more landmarks. In contrast, when trained in enclosures, animals often use the relationship among walls. In the present study, pigeons were trained to find the center of an array of landmarks or a set of short walls that did not block external cues. Expansion tests showed that both groups of pigeons primarily used an absolute distance strategy. However, on rotational tests, pigeons continued to search in the center of the array, suggesting that direction was learned in relation to array. 相似文献

Several research studies suggest the significant role played by metamemory in lexical abilities of both adults and children.
To our knowledge, there have been no studies to date that have explored the role of metamemory (Judgments of Learning) in
fast mapping of novel words by adults. One hundred and twelve undergraduate students were given tasks of fast mapping and
judgments of learning. A one-way Multivariate Analysis of Variance revealed that participants who performed well on fast mapping
had superior global and item-by-item absolute prediction scores compared to poor performers. However, the good and poor performers
did not significantly differ in their item-by-item relative predictive accuracy (Goodman–Kruskal gamma correlations) in the
immediate as well as the delayed judgments of learning conditions. The possible reasons for inferior gamma correlations, the
methodological issues for future research and the clinical implications for the assessment and treatment of adults with lexical
deficits are discussed. 相似文献

A problem in the processing of emotions has long been thought to be strongly associated with the aetiology and maintenance of personality disorders. Previous research has demonstrated a hyposensitivity to the faces expressing fear in those high on the traits of psychopathy, while patients with BPD have been shown to be hypersensitive to expressions in general. However, many previous studies could be explained by a bias in reporting particular expressions rather than a change in sensitivity to these expressions. Using two tasks, the present study examined both the detection and the recognition of four emotional expressions (anger, happy, sad, and fear) in a community sample of males and females. Measures of self-reported psychopathy and Borderline Personality traits were administered. The results showed marked gender differences. Psychopathy was negatively related to performance in both the detection and recognition of fear, but only for males. Borderline Personality traits were positively related to overall performance in the recognitions task, but only for females. The results suggest strong differences in the role that emotional processing might play between the genders. 相似文献

This article reports results from a three-country study of patient perceptions of physician responsiveness. Based on existing research in the medical and social-psychological literatures, we theorized that patients' perceptions of physician responsiveness to their needs would be an important component of the patient–physician relationship and that this construct could be distinguished reliably from more global assessments of patient satisfaction. We then developed a new measure designed to assess these perceptions from the patients' point of view. This measure was administered to large samples of patients in the United States, the United Kingdom, and Canada. Results supported our hypotheses. Patient perception of physician responsiveness significantly predicted both patient satisfaction and subjective health-related problems, over and above effects attributable to general satisfaction. We also noted the absence of significant differences across the three cultures or sex, suggesting that the process we identify has considerable generality. We also describe a short version of our measure that researchers may find useful in a variety of research or clinical settings. 相似文献

The present study investigated the effect of haloperidol-induced mood in normal healthy male volunteers on the retrieval of memories of real-life personal experiences using a between-subjects double-blind design. Forty subjects were required to retrieve past real life experiences associated with a series of stimulus words following administration of a single oral dose of 5mg haloperidol or placebo. The experiences were subsequently rated by subjects for their happiness felt at the time of the original experience. A significant decline in self-reported hedonic tone was observed in subjects given haloperidol. In addition, subjects on placebo recalled a significantly greater percentage of happy memories than subjects who were on haloperidol; a trend for a reverse pattern was observed for unhappy memories. The effects of the drug on the retrieval of memories were only in part mediated by the decline in hedonic tone scores. The effects of haloperidol are interpreted in terms of drug-induced dysphoria. 相似文献

Abstract The performance of agoraphobic and normal subjects is compared across three different types of task (Kamin blocking effect, incidental learning, and choice reaction time) all designed to tap processing of neutral stimuli. Agoraphobics differed from normals on the Kamin blocking task and on one of the two incidental learning measures employed. Choice reaction time performance was the same in both groups. The relevance of these findings for future studies of emotional processing in such subjects is discussed. 相似文献

In this article, we offer some suggestions as to why tetrads and pentads have become the dominant formats for administering multidimensional forced choice (MFC) items but, in turn, raise questions regarding the underlying psychometric model and means of addressing item quality and scoring accuracy. We then focus our attention on multidimensional pairwise preference (MDPP) items and present an item response theory–based approach to constructing and modeling MDPP responses directly, assessing information at the item and scale levels, and a way of computing standard errors for trait scores and estimating scale reliability. To demonstrate the viability of this method for applied use, we show that the correspondence between MDPP scores derived from direct modeling with those obtained using single statement and unidimensional pairwise preference measures administered in a laboratory setting. Trait score correlations and criterion related validities are compared across testing formats and rating sources (i.e., self and other), and the usefulness of our model-based approach is further demonstrated by some illustrative results involving computerized adaptive tests (CAT). 相似文献
